A setup for ultrafast time-resolved x-ray absorption spectroscopy

We present a setup which allows the measurement of time-resolved x-ray absorption spectra with picosecond temporal resoln. on liq. samples at the Advanced Light Source at Lawrence Berkeley National Labs. The temporal resoln. is limited by the pulse width of the synchrotron source. We characterize the different sources of noise that limit the expt. and present a single-pulse detection scheme.
